IV Vitamin Therapy: What It Does, Why It Works, and Why we Use the Myers’ Cocktail
More than hydration—it’s targeted cellular support backed by medical strategy.
IV therapy delivers vitamins directly into your bloodstream so your body absorbs them fully, without relying on digestion. It’s fast, efficient, and often more effective than oral supplements especially when you’re depleted, under stress, or not eating enough.
Why Oral Supplements Aren’t Always Enough
Most people assume they’re getting enough nutrients through food or that taking a multivitamin covers the gaps. But that assumes two things:
Your body can absorb what you ingest
Your needs match the dosage you’re taking
In reality, most people are dealing with at least one of the following:
Gut inflammation or dysfunction that limits nutrient absorption
Chronic stress that depletes essential vitamins and minerals
Hormonal shifts, medications, or digestive conditions that increase demand
Poor conversion of nutrients from inactive to active forms (especially B vitamins)
Even with the best intentions, your body may not be getting or using what it needs.
That’s where IV therapy becomes a clinically useful tool: not a trend, not a shortcut, but a targeted delivery method that works at the cellular level.
What Is IV Vitamin Therapy?
IV (intravenous) therapy is the direct infusion of fluids, vitamins, and minerals into the bloodstream via a vein. This bypasses the digestive tract entirely, allowing for:
Immediate absorption
Near 100% bioavailability
Direct nutrient delivery to cells
Faster symptom relief and systemic support
We use it at Core to address both acute symptoms (fatigue, illness recovery, dehydration) and chronic imbalances (burnout, low energy, micronutrient depletion).
It’s especially helpful for clients whose systems are under stress, recovering, or adapting to weight loss or hormonal shifts.
Why We Use the Myers’ Cocktail
The Myers’ Cocktail is the most established IV therapy formulation in functional medicine. Developed by Dr. John Myers in the 1960s, it was originally used to treat conditions like fatigue, migraines, muscle cramps, and immune dysfunction.
Oranges are a great source of Vitamin C but when your body needs extra immune support, IV therapy delivers a higher dose directly into your bloodstream for maximum absorption and faster impact. It's a powerful way to support your system when you're run down, recovering, or preparing for travel.
At Core, we use a medical-grade version of this cocktail with high-potency nutrients, including:
Vitamin C – Supports immune defense, collagen synthesis, antioxidant function, and recovery
Vitamin B12 – Essential for red blood cell production, neurological health, mood, and metabolism
B-complex (B1, B2, B3, B5, B6) – Critical for energy production, hormone regulation, and nervous system function
Magnesium – Regulates muscle relaxation, blood pressure, sleep quality, and insulin sensitivity
Calcium – Supports muscular contractions and bone metabolism
This blend is versatile, effective, and well-tolerated by most people.
It’s our most commonly used base formula for a reason; it meets your system where it is, and gives it what it needs to reset.What IV Therapy Helps With (and Why)
We use IV therapy to support a range of systems—not just one symptom. Common reasons clients receive infusions include:
Energy depletion: Nutrient deficiencies—especially in B12, magnesium, and B-complex—can impair mitochondrial function, slow ATP production, and cause chronic fatigue even in “healthy” individuals. IV therapy bypasses absorption issues and gives your cells the raw materials needed to make energy again.
Immune support: Vitamin C and B12 play essential roles in both the innate and adaptive immune response. We often use the Myers’ blend pre-travel, post-illness, or seasonally for clients looking to stay ahead of viral or bacterial exposure.
Dehydration and electrolyte loss: Illness, alcohol use, stress, heat exposure, and even GLP-1 medications can cause or worsen dehydration. IV therapy restores hydration, improves blood flow, and helps normalize blood pressure, temperature regulation, and digestion.
Poor recovery (post-surgical, post-illness, or post-training): Magnesium and Vitamin C assist with soft tissue healing, reduce inflammation, and improve sleep: key for physical and cognitive repair.
Weight loss support: Clients on GLP-1s often struggle with low appetite and reduced nutrient intake. IV therapy helps correct deficiencies, improve energy, and support liver detoxification during fat breakdown. It’s a tool we use to keep your metabolism steady even while your intake is low.
Chronic inflammation and oxidative stress: Vitamin C acts as a systemic antioxidant, neutralizing free radicals and supporting the body’s natural detox and repair processes. When paired with glutathione (optional), it helps reduce internal inflammation that can slow weight loss and impair skin and brain health.
What to Expect During Your Treatment at Core
IV therapy at Core is:
Medically overseen
Professionally administered
Calm, private, and efficient
Tailored to your symptoms, medications, and energy level
Each session takes approximately 45-60 minutes. We monitor your comfort, customize your dosing if needed, and explain exactly what you’re getting and why.
You’ll feel the effects gradually: most clients report mental clearness, reduced fatigue, better sleep, or improved digestion within 24–48 hours. (That isn’t a spike of energy, btw… it’s a cellular reset).
Clinical FAQ
Can IV therapy replace supplements? It can temporarily compensate for low intake or absorption—but long-term nutritional habits still matter. IV therapy is a tool, not a substitute.
How often should I get an IV? Depends on your symptoms. Some clients come in weekly during recovery or illness; others come monthly for prevention. We’ll guide you based on your needs.
Is it safe? Yes, when administered by trained professionals with proper intake and dosage protocols. We assess medications, allergies, and medical history before your treatment.
You Can’t Build Energy on Deficiency
Your body can’t run on caffeine, stress, and willpower forever. IV therapy isn’t about “boosting” temporarily, it’s about replenishing deeply.
We use the Myers’ Cocktail because it’s targeted, proven, and flexible enough to support a wide range of needs: from fatigue to immune recovery to foundational nutrient repletion.
If you’re feeling drained, foggy, inflamed, or under-nourished despite doing everything right? This might be your reset point.
